I wasn't able to find anything on the ESPN web site that details anything about their final table coverage other than Monday at 8:00 ET/7:00 CT on ESPN2 (3 hours) and Tuesday at 9:00 ET/8:00 CT on ESPN (2 hours).
I am padding those recordings by 3 hours each, plus I am recording about 4 hours of those respective channels that air following those time blocks.
I seem to recall that last year's final table took FAR, FAR longer than just 5 hours total, and I don't have any idea how long they'll stick with coverage either night. I'm assuming they plan on Monday night going as long as it takes to get down to X number of players, and Tuesday night being covered until there is a winner.
Bottom line - if you want to watch it all, make plans that coverage will probably run over both nights!
